Second video card in Mac Pro

[DELTAsnake]

I'm thinking about putting an old nVidia card in my Mac Pro for PhysX under Windows 7. Theres a way detailed on the AMD forums to get a PC to use a AMD card as graphics and a nVidia card just as Physx in the one machine. While this should all be fine to do in a Mac Pro under Windows 7, what happens when I reboot and go back into OSX? Would OSX ignore the old nVidia card or would there be some kind of conflict?

I'd like to try this out for a bit of fun and seeing what a Mac Pro is really capable of, but if it will cause problems for OSX I won't do it.

As long as your monitor is connected to the AMD card, there shouldn't be any issues.

Keep in mind, this setup sometimes has issues when running an AMD graphics card. NVidia is trying to lock it down so that if any AMD card is in your system it won't work.
